First Claim
Patent Images
1. A method of controlling discontinuous reception between a mobile radio communications network device and a mobile radio communications device within a mobile radio communications network, comprising:
- controlling the magnitude of the discontinuous reception period in a manner responsive to the velocity of movement of the mobile radio communications device within the network; and
determining the velocity at the mobile radio communications network device by way of a timing off-set signal,wherein the velocity is determined by means of determining a change in a timing advance value, andwherein the controlling of the magnitude is performed such that the magnitude of the discontinuous reception period increases as the velocity of the mobile radio communications device decreases.

Abstract
The invention provides for a method of controlling discontinuous reception between a mobile radio communications network device and a mobile radio communications device within a mobile radio communications network and including the step of controlling magnitude of the discontinuous reception period in a manner responsive to the velocity of movement of the mobile radio communications device within the network such that a decrease in velocity can lead to an increase in the discontinuous reception period employed by the devices.

9. A mobile radio communications network device arranged for discontinuous reception with a mobile radio communications device within a mobile radio communications network, comprising:
-
a first unit that determines the velocity of movement of the mobile radio communications device; a second unit that compares the determined velocity with threshold values; and a third unit that signals to the mobile radio communications device for a change in discontinuous reception period responsive to the result of said comparison, wherein the velocity is determined by reference to a timing off-set value, wherein the off-set value is determined with reference to a change in a timing advance value, and wherein the third unit increases the discontinuous reception period as the determined velocity decreases. - View Dependent Claims (10, 11, 12, 13)
